FIELD OF THE INVENTION

[0001] The present invention relates to 1,8-naphthyridine derivatives, pharmaceutical compositions containing them, and their use for treating diabetes and related disorders in a subject.

DESCRIPTION OF THE RELATED ART

[0002] Diabetes is characterized by impaired glucose metabolism manifesting itself among other things by an elevated blood glucose level in the diabetic patient. Underlying defects lead to a classification of diabetes into two major groups: type 1 diabetes, or insulin dependent diabetes mellitus (IDDM), arises when patients lack insulin-producing beta-cells in their pancreatic glands. Type 2 diabetes, or non-insulin dependent diabetes mellitus (NIDDM), occurs in patients with impaired beta-cell function and alterations in insulin action.

[0003] The current treatment for type 1 diabetic patients is the injection of insulin, while the majority of type 2 diabetic patients are treated with agents that stimulate beta-cell function or with agents that enhance the tissue sensitivity of the patients towards insulin. The drugs presently used to treat type 2 diabetes include alpha-glucosidase inhibitors, insulin sensitizers, insulin secretagogues, and metformin.

[0004] Over time almost one-half of type 2 diabetic subjects lose their response to these agents. Insulin treatment is instituted after diet, exercise, and oral medications have failed to adequately control blood glucose. The drawbacks of insulin treatment are the need for drug injection, the potential for hypoglycemia, and weight gain.

[0005] Because of the problems with current treatments, new therapies to treat type 2 diabetes are needed. In particular, new treatments to retain normal (glucose-dependent) insulin secretion are needed. Such new drugs should have the following characteristics: dependency on glucose for promoting insulin secretion, i.e., compounds that stimulate insulin secretion only in the presence of elevated blood glucose; low primary and secondary failure rates; and preservation of islet cell function. The strategy to develop the new therapy disclosed herein is based on the cyclic adenosine monophosphate (cAMP) signaling mechanism and its effects on insulin secretion.

[0006] Metabolism of glucose promotes the closure of ATP-dependent K+ channels, which leads to cell depolarization and subsequent opening of Ca++ channels. This in turn results in the exocytosis of insulin granules. cAMP is a major regulator of glucose-stimulated insulin secretion. However, it has little if any effects on insulin secretion in the absence of or at low glucose concentrations (Weinhaus, A., et al., Diabetes 47: 1426-1435 (1998)). The effects of cAMP on insulin secretion are thought to be mediated by a protein kinase A pathway.

[0007] Endogenous secretagogues like pituitary adenylate cyclase activating peptide (PACAP), VIP, and GLP1 use the cAMP system to regulate insulin secretion in a glucose-dependent fashion (Komatsu, M., et al., Diabetes 46: 1928-1938, (1997)). Also, phosphodiesterases (PDEs) are known to be involved in the regulation of the cAMP system.

[0008] PACAP is a potent stimulator of glucose-dependent insulin secretion from pancreatic beta cells. Three different PACAP receptor types (R1, R2, and R3) have been described (Harmar, A., et al., Pharmacol. Reviews 50: 265-270 (1998)). The insulinotropic action of PACAP is mediated by the GTP binding protein Gs. Accumulation of intracellular cAMP in turn activates nonselective cation channels in beta cells increasing [Ca++]i, and promoting the exocytosis of insulin-containing secretory granules.

[0009] Vasoactive intestinal peptide (VIP) is a 28 amino acid peptide that was first isolated from hog upper small intestine (Said and Mutt, Science 169: 1217-1218, 1970; U.S. Pat. No. 3,879,371). This peptide belongs to a family of structurally related, small polypeptides that includes helodermin, secretin, the somatostatins, and glucagon. The biological effects of VIP are mediated by the activation of membrane-bound receptor proteins that are coupled to the intracellular cAMP signaling system. These receptors were originally known as VIP-R1 and VIP-R2, however, they were later found to be the same receptors as PACAP-R2 and PACAP-R3.

[0010] GLP-1 is released from the intestinal L-cell after a meal and functions as an incretin hormone (i.e., it potentiates glucose-induced insulin release from the pancreatic beta cell). It is a 37-amino acid peptide that is differentially expressed by the glucagon gene, depending upon tissue type. The clinical data that support the beneficial effect of raising cAMP levels in &bgr;-cells have been collected with GLP-1. Infusions of GLP1 in poorly controlled type 2 diabetics normalized their fasting blood glucose levels (Gutniak, M., et al., New Eng. J. Med. 326:1316-1322, (1992)) and with longer infusions improved the beta cell function to those of normal subjects (Rachman, J. et al., Diabetes 45: 1524-1530, (1996)). A recent report has shown that GLP-1 improves the ability of &bgr;-cells to respond to glucose in subjects with impaired glucose tolerance (Byrne M., et al., Diabetes 47: 1259-1265 (1998)). All of these effects, however, are short-lived because of the short half-life of the peptide.

[0142] General Preparative Methods

[0143] The compounds of the invention may be prepared by use of known chemical reactions and procedures. Nevertheless, the following general synthetic schemes are presented to aid the reader in synthesizing compounds of this invention, with more detailed particular examples being presented below in the experimental section describing the working examples.

[0144] In general, compounds of Formula (I) (R4 is ═O) may be prepared from the appropriately substituted nicotinic acid through several routes summarized in Flow Diagram I to IV. Compounds of Formula (II) (R4′ is ═O) may be prepared from the appropriately substituted nicotinic acid through the route summarized in Flow diagram V. The close analogy between Flow Diagram I and V demonstrates that the routes used to synthesize Formula (I) may be applied to synthesize Formula (II). The routes shown in Flow Diagram II to IV maybe used to synthesize Formula (II) from appropriately substituted nicotinic acid. 5 6 7 8 9

[0145] The nicotinic acids used in the above flow diagrams could be purchased from commercial sources, prepared according to Flow Diagram VI, or prepared according to literature in this field (Biorg. Med. Chem. Lett. 2001, 475-477; J. Prakt. Chem. 2002, 33; Eur. J. Org. Chem. 2001, 1371; J. Org. Chem. 2000, 65, 4618; J. Med. Chem. 1997, 40, 2674; Bioorg. Med. Chem. Lett. 2000, 10, 1151; U.S. Pat. No. 3,838,156, etc.). 10

[0146] Further manipulations of Formula (I) (when R4 is ═O) and (II) (when R4′ is ═O) could lead to more diversely substituted compounds. These manipulations include aromatic nucleophilic substitutions, metal-mediated couplings, reductions, oxidations, amide formations, etc.

Commonly used prodrugs are designed to take advantage of the major drug biotransformation reactions and are also to be considered within the scope of the invention. Major drug biotransformation reactions include N-dealkylation, O-dealkylation, aliphatic hydroxylation, aromatic hydroxylation, N-oxidation, S-oxidation, deamination, hydrolysis reactions, glucuronidation, sulfation and acetylation (see Goodman and Gilman's The Pharmacological Basis of Therapeutics (Ninth Edition), editor Molinoff et al., publ. by McGraw-Hill, pages 11-13, (1996), which is hereby incorporated by reference).

[0166] Dosages and Treatment Regimen

[0167] Dosage levels of the compounds of this invention typically are from about 0.001 mg to about 10,000 mg daily, preferably from about 0.005 mg to about 1,000 mg daily. On the basis of mg/kg daily dose, either given in a single dose or in divided doses, dosages typically range from about 0.001/75 mg/kg to about 10,000/75 mg/kg, preferably from about 0.005/75 mg/kg to about 1,000/75 mg/kg.

[0168] The total daily dose of each drug can be administered to the patient in a single dose, or in multiple subdoses. Typically, subdoses can be administered two to six times per day, preferably two to four times per day, and even more preferably two to three times per day. Doses can be in immediate release form or sustained release form sufficiently effective to obtain the desired control over the diabetic condition.

[0169] The dosage regimen to prevent, treat, give relief from, or ameliorate a diabetic condition or disorder, or to otherwise protect against or treat a diabetic condition with the combinations and compositions of the present invention is selected in accordance with a variety of factors. These factors include, but are not limited to, the type, age, weight, sex, diet, and medical condition of the subject, the severity of the disease, the route of administration, pharmacological considerations such as the activity, efficacy, pharmacokinetics and toxicology profiles of the particular inhibitors employed, whether a drug delivery system is utilized, and whether the inhibitors are administered with other active ingredients. Thus, the dosage regimen actually employed may vary widely and therefore deviate from the preferred dosage regimen set forth above.

[0170] Pharmaceutical Compositions

[0171] For the prophylaxis or treatment of the conditions and disorders referred to above, the compounds of this invention can be administered as the compound per se. Alternatively, pharmaceutically-acceptable salts are particularly suitable for medical applications because of their greater aqueous solubility relative to that of the parent compound.

[0172] The compounds of the present invention also can be administered with an acceptable carrier in the form of a pharmaceutical composition. The carrier must be acceptable in the sense of being compatible with the other ingredients of the composition and must not be intolerably deleterious to the recipient. The carrier can be a solid or a liquid, or both, and preferably is formulated with the compound as a unit-dose composition, for example, a tablet, which can contain from about 0.05% to about 95% by weight of the active compound(s) based on a total weight of the dosage form. Other pharmacologically active substances can also be present, including other compounds useful in the treatment of a diabetic condition.

[0173] The active compounds of the present invention may be administered by any suitable route, preferably in the form of a pharmaceutical composition adapted to such a route, and in a therapeutically effective dose for the treatment intended. The active compounds and compositions, for example, may be administered orally, sublingually, nasally, pulmonarily, mucosally, parenterally, intravascularly, intraperitoneally, subcutaneously, intramuscularly or topically. Unit dose formulations, particularly orally administrable unit dose formulations such as tablets or capsules, generally contain, for example, from about 0.001 to about 500 mg, preferably from about 0.005 mg to about 100 mg, and more preferably from about 0.01 to about 50 mg, of the active ingredient. In the case of pharmaceutically acceptable salts, the weights indicated above for the active ingredient refer to the weight of the pharmaceutically active ion derived from the salt.

[0174] For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, a capsule, a suspension, an emulsion, a paste, a solution, a syrup or other liquid form. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. If administered by mouth, the compounds may be admixed with, for example, lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration.

[0175] Oral delivery of the compounds of the present invention can include formulations, as are well known in the art, to provide immediate delivery or prolonged or sustained delivery of the drug to the gastrointestinal tract by any number of mechanisms. Immediate delivery formulations include, but are not limited to, oral solutions, oral suspensions, fast-dissolving tablets or capsules, sublingual tablets, disintegrating tablets and the like. Prolonged or sustained delivery formulations include, but are not limited to, pH sensitive release of the active ingredient from the dosage form based on the changing pH of the small intestine, slow erosion of a tablet or capsule, retention in the stomach based on the physical properties of the formulation, bioadhesion of the dosage form to the mucosal lining of the intestinal tract, or enzymatic release of the active drug from the dosage form. The intended effect is to extend the time period over which the active drug molecule is delivered to the site of action by manipulation of the dosage form. Thus, enteric-coated and enteric-coated controlled release formulations are within the scope of the present invention. Suitable enteric coatings include cellulose acetate phthalate, polyvinylacetate phthalate, hydroxypropylmethyl-cellulose phthalate and anionic polymers of methacrylic acid and methacrylic acid methyl ester.

[0176] Pharmaceutical compositions suitable for oral administration can be presented in discrete units, such as capsules, cachets, lozenges, or tablets, each containing a predetermined amount of at least one compound of the present invention; as a powder or granules; as a solution or a suspension in an aqueous or non-aqueous liquid; or as an oil-in-water or water-in-oil emulsion. As indicated, such compositions can be prepared by any suitable method of pharmacy which includes the step of bringing into association the inhibitor(s) and the carrier (which can constitute one or more accessory ingredients). In general, the compositions are prepared by uniformly and intimately admixing the inhibitor(s) with a liquid or finely divided solid carrier, or both, and then, if necessary, shaping the product. For example, a tablet can be prepared by compressing or molding a powder or granules of the inhibitors, optionally with one or more accessory ingredients. Compressed tablets can be prepared by compressing, in a suitable machine, the compound in a free-flowing form, such as a powder or granules optionally mixed with a binder, lubricant, inert diluent and/or surface active/dispersing agent(s). Molded tablets can be made, for example, by molding the powdered compound in a suitable machine.

[0177] Liquid dosage forms for oral administration can include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents commonly used in the art, such as water. Such compositions may also comprise adjuvants, such as wetting agents, emulsifying and suspending agents, and sweetening, flavoring, and perfuming agents.

[0178] Pharmaceutical compositions suitable for buccal (sub-lingual) administration include lozenges comprising a compound of the present invention in a flavored base, usually sucrose, and acacia or tragacanth, and pastilles comprising the inhibitors in an inert base such as gelatin and glycerin or sucrose and acacia.

[0179] Formulations for parenteral administration, for example, may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art.

[0180] Pharmaceutically acceptable carriers encompass all the foregoing and the like. The pharmaceutical compositions of the invention can be prepared by any of the well-known techniques of pharmacy, such as admixing the components. The above considerations in regard to effective formulations and administration procedures are well known in the art and are described in standard textbooks.

[0487] Biological Evaluation

[0488] Demonstration of the activity of the compounds of this invention is accomplished through in vitro, ex vivo and in vivo assays that are well known in the art.

[0489] In Vivo Test Procedure:

[0490] Male Wistar rats (270-330 g) were fasted overnight and then given either vehicle or compound by oral gavage. Two or three hours later, the rats were given an intraperitoneal dose of glucose (2 g/kg). The rats were tail-bled for glucose using a Glucometer (Bayer Corporation, Mishawaka, Ind.) just prior to the glucose dose and 15, 30 and 60 minutes afterward. The area under the glucose curve was calculated by the trapezoidal method for both the vehicle and treated animals, and the percent reduction in the glucose AUC by the compound calculated. A typical positive effect of the compound results in a 12-20% reduction in the AUC relative to the AUC of the vehicle-treated group. Compounds of present invention were found to have a blood glucose lowering effect in this in vivo assay.

[0491] The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing examples are included by way of illustration only. Accordingly, the scope of the invention is limited only by the scope of the appended claims.
